string theory

what is string theory ? string theory is theoretical and it  is just like a mathematical tool other than classical physics like a cosmology . string theory suggest that smallest thing in not point particle instead of that it is a string which are one dimensional extended object . as in above fig the whole black part is universe and it is subdivided into small thread or string which is in blue color . small string connect together and make a anything around us . These string propagate through space and interact with each other , such string have charge and mass. they possess a vibration by which it communicate with each other . such vibrational state of the string include ;- 1. Gravition   2. Quantam mechanical particle 3. Gravitational force 1. Gravition; - it is hypothetical or imaginative theory they are expected to be massless it is belived            that something like gravitation and spin around space. 2. quantam mechnical particle ;- In last arti
what is hyperloop? hyperloop is a high-speed transport system in which passengers sit in a pressurized capsule operates in a sealed near vacuum environment the sealed near vacuum environment the propulsion system is still to be chosen from a no of option two of which are magnetic levitation or air pressure. ELON MUSK proposes this idea which is known as the fifth mode of transport HYPERLOOP. so far we have been using trains, cars, plane, boat and technically rockets. HISTORY It been a very astonishing that idea seem to be new and futuristic  is actully a idea has been proposed and expermiented by a British mechanical engineer and inventor GEORGE MEDHURST in 1812  . Medhurst wrote a book detailing his idea of transporting passengers and goods through airtight tubes using air propulsion .the first hyperloop transport system was the crystal palace, pneumatic railways . This  operated by three tunnels in London in 1864 by powered by steam engine . The line actual
Quantum mechanics begin with a conflict of what exactly light is ? One experiment say that it is a wave in nature and another experiment says it is particle. After some experiment it come with a strange concept that light was both (particle and wave). Such a thought had started new thing in called quantum mechanics. One of the most important clues that light had to be more than just a wave was what’s known as The ultraviolet catastrophe . Now new thought begin how object radiate heat .Basis of this thought new law came out Stefan - Boltzmann law ,  that the total radiant heat energy emitted from a surface is proportional to the fourth power of its absolute temperature. Object actually radiate energy that covers a whole range of frequencies on the electromagnetic spectrum all different kind of light .on the basis of above law :- Black bodies –means a body which absorb light without reflecting any and radiate energy accordingly. not  all the energy coming from a bla
